Measurements of functional, hemographic, and blood flow parameters use a multiple echo or spin echo gradient pulse sequence whereby an early echo is acquired near the beginning of the pulse sequence which avoids saturation effects and a later echo near the end of the pulse sequence which can provide information with more sensitivity to a contrast agent for a susceptibility weighted image.

An ultrasound image acquisition device initiates acquisition of anatomical images of a portion of patient anatomy in response to a heart rate related synchronization signal. The ultrasound image acquisition device includes multiple ultrasound transducers for generating sound waves. The ultrasound transducers are arranged in different transducer groups oriented to enable acquisition of different ultrasound imaging information used in generating a single composite ultrasound image. A synchronization processor derives the heart rate related synchronization signal from a patient cardiac function blood flow related parameter. The synchronization signal enables adaptive activation of a particular group of the different transducer groups for acquisition of ultrasound imaging information used in generating the single composite ultrasound image. A display processor presents the single composite ultrasound image, acquired by the ultrasound image acquisition device, to a user on a reproduction device.

The invention discloses a preparation method of a multifunctional vascular stent. Firstly, a dopamine coating is prepared on the surface of a vascular stent through self-polymerization of dopamine; Graphene was immobilized on the surface of the dopamine-coated vascular stent to obtain a heparin-loaded vascular stent; finally, the vascular stent was immersed in a rapamycin solution to fully absorb and load rapamycin to obtain a multifunctional vascular stent. Due to the antibacterial effect of chitosan and the effect of promoting endothelial cell growth, the anticoagulant effect of heparin, the effect of selectively promoting endothelial cell growth and the antiproliferative effect of rapamycin, the vascular stent prepared by the present invention will be prepared from multiple ways Inhibit the clinical complications of stent implantation, thereby improving the application effect of vascular stents.

The invention relates to a serum albumin with a metal chelating function as well as a preparation method and an application in inhibition for the aggregation of beta-amyloid proteins. The serum albumin with the metal chelating function is obtained through modifying 1,4-butanediol diglycidyl ether on an amino group on the surface of a serum albumin at first, and then modifying a metal chelating agent iminodiacetic acid on an epoxy group of 1,4-butanediol diglycidyl ether, and the average modification number of iminodiacetic acid on each serum albumin ranges from 2 to 40. According to the serum albumin with the metal chelating function, which is disclosed by the invention, the chelating capacity of the serum albumin for metal ions is improved, and then the self-aggregation of the beta-amyloid proteins and an aggregation process of the beta-amyloid proteins under the induction of the metal ions are inhibited, and the cytotoxicity of beta-amyloid protein aggregates is reduced. The serum albumin with the metal chelating function is used for a medicine for treating the diseases related to beta-amyloid protein aggregation. The medicine is used for treating and slowing down Alzheimer disease and other diseases.
